Subject: ath79: fix link for long cables with OCEDO Raccoon
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4551bfd91f31be5987727c77e58333fa06ba3acd;p=openwrt%2Fstaging%2Fnbd.git

ath79: fix link for long cables with OCEDO Raccoon

The OCEDO Raccoon had significant packet-loss with cables longer than 50
meter. Disabling EEE restores normal operation.

Also change the ethernet config to reduce loss on sub-1G links.
